Tommy, I remember I used the doc from Debian page as a starting point and adapted to Fedora. I deactivated the NetworkManager on the WLAN interface and prepared many commands to add to rc.local. I remember I had issues with routing when using NAT network (it was a KVM host only, not an oVirt instance) despite it woked fine with bridge connections. I will look if I have a copy in my old backups. It was a long time ago.

Hi Tommy, Two comments for your appreciation: 1st: Technically, it is possible. You can configure your wireless network as a bridge and use it as you wish. I did it in my laptop a long time ago to test KVM instances. 2nd: Taking security in focus, it is not a recommendation to use wireless cards in servers. Wireless connections can be easily attacked since there is no need for someone to have logical access to your server.

Hi, In my little experience, no you can't, I tried that a while ago it didn't work, there is some old tutorial on Debian but it didn't work for me. May be what you can do is share you wireless connexion with your wired connexion (where you can create your bridge). And play with the firewall to expose the ovirt webadmin-ui to your external network. Regards.

Moving datacenters & IP addresses with minimal downtime
by David White 23 Aug '21

23 Aug '21

So it looks like I'm going to move to a new datacenter. I went into somewhere cheap on a month-to-month contract earlier this year, and they've been a pain to deal with. At the same time, I've grown a lot faster than expected, so I've decided to move into a better, more reputable datacenter sooner rather than later. I currently have HCI with 3 servers. Within the cluster, I can tolerate a host "failure", so I can run on 2 servers. I have a 4th server that I haven't really been doing anything yet, but I think will be a good asset to me as I move, to keep things to a minimum. One of my production nodes, as well as my 4th server don't have the right storage, so if/when I move things, I'll need to configure Gluster to run on a single node for a time. I'd like to ask about best practices here. Before I move any hardware, I'm thinking about removing 1 of my 3 production servers from the existing HCI cluster, and installing a NEW hyperconverged single node onto this production server with Gluster storage. Then, add my 4th server to that new oVirt environment. Once I did that, I'm wondering if I could clone 100% of the VMs from the 1 environment over to the other. Once that was done, I could move one of my oVirt clusters to the new datacenter, update DNS for the virtual servers, run a final rsync, and I'm done -- then I would just move the other two servers, do a fresh install of oVirt, and add them to the new cluster. Is this possible? Is there a better way to do this move? Thanks,David Sent with ProtonMail Secure Email.

Unable to change Mail Recipient for Event Notifications
by Rodrigo G. López 23 Aug '21

23 Aug '21

Hello all, There seems to be a problem with oVirt 4.4.7.7 when modifying the Mail Recipient field in the Add Event Notification modal with the `admin' user. It defaults to `root@localhost' and I can't change it no matter what I try. It happens whether I check some Events for Notification or not, and the ovirt-engine-notifier service is also running healthily. Is this known behavior? What am I missing? I'm following §21 of the Administration Guide. Best, -rodri

I can't download console.rdp on VM Portal with Firefox
by Dominique D 20 Aug '21

20 Aug '21

I am testing the lastest version of ovirt-engine 4.4.7.7-1 before updating. when I log into the VM portal and want to download the Remote Destop file (console.rdp) from a Windows VM, the file I receive is console.vv instead of console.rdp. So I have to rename the file to console.rdp. This problem is only with firefox. Edge and google chrome don't have this problem. Do you know why ?

Faster local disk for VM
by Shantur Rathore 20 Aug '21

20 Aug '21

Hi Users, Does oVirt support node local disk cache or scratch / transient disk for faster disk access? The idea is similar to options we get on cloud where one can attach fast node local scratch disk/ssd to the VM which gets deleted when VM dies. Thanks in advance. Kind Regards, Shantur

Ovirt-4.4.7 Adding host to existing cluster will attempt to run ovirt-hosted-engine-setup
by Paul-Erik Törrönen 15 Aug '21

15 Aug '21

I have an existing oVirt-installation to which I want to add a new host (from the UI). However the adding fails because oVirt tries to then install the ovirt-hosted-engine-setup despite the fact that in the New host-dialog I left the Choose hosted engine deployment action as None. As a result the installation then aborts: 2021-08-15 13:17:37 EEST - TASK [ovirt-host-deploy-vdsm : Install ovirt-hosted-engine-setup package] ****** 2021-08-15 13:17:37 EEST - 2021-08-15 13:17:37 EEST - fatal: [new.host]: FAILED! => {"changed": false, "failures": ["No package ovirt-hosted-engine-setup available."], "msg": "Failed to install some of the specified packages", "rc": 1, "results": []} 2021-08-15 13:17:37 EEST - { "status" : "OK", "msg" : "", "data" : { "uuid" : "98a244fb-15da-4192-a8fc-b23a5e5b7594", "counter" : 55, "stdout" : "fatal: [new.host]: FAILED! => {\"changed\": false, \"failures\": [\"No package ovirt-hosted-engine-setup available.\"], \"msg\": \"Failed to install some of the specified packages\", \"rc\": 1, \"results\": []}", "start_line" : 47, "end_line" : 48, "runner_ident" : "fe710372-fdb1-11eb-81f0-ecf4bb63099f", "event" : "runner_on_failed", "pid" : 24931, "created" : "2021-08-15T10:17:35.963320", "parent_uuid" : "ecf4bb63-099f-2448-1b83-0000000001a7", "event_data" : { "playbook" : "ovirt-host-deploy.yml", "playbook_uuid" : "8f70f945-4008-4159-b469-7ff04c9c242b", "play" : "all", "play_uuid" : "ecf4bb63-099f-2448-1b83-000000000006", "play_pattern" : "all", "task" : "Install ovirt-hosted-engine-setup package", "task_uuid" : "ecf4bb63-099f-2448-1b83-0000000001a7", "task_action" : "yum", "task_args" : "", "task_path" : "/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml:6", "role" : "ovirt-host-deploy-vdsm", "host" : "new.host", "remote_addr" : "new.host", "res" : { "msg" : "Failed to install some of the specified packages", "failures" : [ "No package ovirt-hosted-engine-setup available." ], "results" : [ ], "rc" : 1, "invocation" : { "module_args" : { "name" : [ "ovirt-hosted-engine-setup" ], "state" : "present", "allow_downgrade" : false, "autoremove" : false, "bugfix" : false, "disable_gpg_check" : false, "disable_plugin" : [ ], "disablerepo" : [ ], "download_only" : false, "enable_plugin" : [ ], "enablerepo" : [ ], ...

about the clonetype of the vm disk when vm is cloned from template
by Tommy Sway 14 Aug '21

14 Aug '21

There are some options for clone disk for other platform like oVirt. --clonetype [thin|full] A thin clone uses copy-on-write (COW) reflinked clone meaning it is dependent on the base template, but enables rapid cloning. Full clone will make a full physical copy hence not be dependent on the base template. Thin clone uses less space and will not be as performant as full clone, especially under heavy write workloads. By default a thin clone is created, great for testing; should be avoided in production environments. I want to know which type is oVirt using when we clone vm from template ?
